Black Friday Blackout nightmare is over

[Chi Stallion]

The Black Friday blackout nightmare is finally over. I fought alota tough battles, but this **** was tough almost had me throwing in the towel.
On Black Friday night while I had my sounds on full blast, my corner, speed cluster, eatc lights, floor shifter lights and rear taillights all went out. It had me puzzled. So I checked the fuse box underneath the dash and fuse box 21 was blown out. Put in a new 15amp fuse and as soon I turned the headlight switch it would pop the fuse. It took about 2 weeks to figure out where the issue was coming from.
The issue was coming from a wire in license plate light which could of been caused from the vibration of the subwoofer. Also the harness that the lcm connects to also had a little slice wire but the issue was coming from the headlight switch not getting any power. So my car audio tech traced the wire coming from the headlight switch and it lead to the rear license plate light.
I seen a few post on mm.net that had the same exact issue as me with fuse box 21 and his issue came from the passenger fog light harness.
I'm so happy I can drive car now and won't worry about no more fuses.

Glad you figured it out. Electrical gremlins can be hair pullers.

Interesting as I just had the same issue not too long ago and I also have a subwoofer in my trunk that I had installed a little over a year ago.

I had this same fuse location 21 blow out earlier this year in February and I just replaced the fuse with a 15a and didn't think nothing of it til late November when I put my sound system in.

I also put soundskins sound deadener all on the trunk floor, side quarter panels, inside rear cabin and will do the trunk lid next. I had recently replaced my whole trunk floor, which I do feel like I'm one of the very few ppl in the world that done this. I do feel like the soundskins deadener made a world of difference, especially with all the roadside noise on the highway the car feels more planted on the floor even with strong winds the rear doesn't move with strong winds at highway speeds. It's not heavy and stronger than regular dynamat. I also put some high end xs power titan 8 batteries which I feel like are the best batteries I ever owned they only weigh 10 pounds each!! The box is ported with the port facing the rear cabin, birchwood which is stronger and lighter than regular mdf which cost more. Im running a kicker solo x 12 with the legendary rockford fosgate 1501bd all the air moves inside the car how it should. Also that 8" inch hole for the factory subwoor helps alot with air getting inside the car through the rear cabin with the port facing inside. Here's a few pics. I don't post much cause I'm more active on the fb marauder group pages but mm.net is still home.

I don't have an elaborate setup like that. Just a Kicker 8" solobaric in a sealed box being pushed by an Alpine mono amp at 450 watts.
